Replace PTFE Mixer and Agitator Bearings with Vespel® CR-6100 for Maximized Performance and Service Life

Mixers and agitators are frequently built with PTFE or filled-PTFE shaft bearings. PTFE-based materials are used because they offer excellent chemical resistance and low friction. Unfortunately, these materials have significant shortcomings in their dimensional stability.
Vespel® CR-6100 offers similar chemical and frictional performance, combined with excellent dimensional stability.

Use DuPont Vespel CR-6100 in Cryogenic Ethane and Methane Pumps

Ethane and methane are the lightest light hydrocarbons. In liquid form, they are most commonly found at cryogenic temperatures down to -160⁰C. The cryogenic temperatures combined with the low viscosity and flashing nature of the products makes cryogenic ethane, methane, and LNG pumps a challenging pump application. Vespel® CR-6100 is an ideal material for wear rings and bearings in cryogenic LNG service.

Consider DuPont™ Vespel® CR-6100 for API Separator Bearings

One of the first waste treatments steps in a refinery or petrochemical plant is the API Separator, which uses differences in specific gravity to separate oil, water, and suspended solids. The oil rises to the top, the solids settle at the bottom, and a layer of water is in between. The oil is typically returned to the plant for reprocessing, the sediment is scraped off the bottom, and the water is sent onward for further waste treatment.

How Much Does it Cost to Run a Pump?

Over the past few months, we have discussed the efficiency gains which can be attained from using Vespel® CR-6100 wear rings with reduced clearance in centrifugal pumps. One of the common questions we have received is “what is the payback period for the investment?” Here is your answer …

Grease Electric Motors for Life!

Imagine you could grease your electric motor bearings for life. You could change bearings during electrical inspection or overhaul and let them run for another 10 or 20 years. No more headaches trying to manage the preventive maintenance schedule. No more oxidation of the lubricant. No more worrying whether there was too much or too little grease in the bearings. This is possible today using DuPont™ Krytox® lubricant.
